Abstract

The purpose of this work is the study the ability of the plant material Aloe vera to act as natural coagulant using raw water obtained from a drinking water treatment plant (Mila, Algeria). Different solvents such as: NaCl; NaOH and HCl were used as chemical activators to extract the active components from the Aloe vera plant, and different coagulation-flocculation experiments were conducted in a jar test apparatus to evaluate the performance of the extracted coagulant. Also, the effect of coagulant dose on some water parameters such as turbidity, pH, total alkalinity and organic matter were investigated. The results showed that the use of coagulants obtained by using different solvents increases the coagulation efficiency compared to the coagulant obtained from the raw material, for example the maximum turbidity removal efficiency was 28.23, 78.07, 83.46 and 85.15% when using powdered Aloe vera (raw material), AV-NaCl (0.5 M), AV-NaOH (0.05 M) and AV-HCl (0.05 M), respectively. The results defined, that the residual turbidity obtained in this work, where the Aloe vera was used (after treatment by solvents) produced a turbidity lower than the Algerian standard (5 NTU) with initial turbidity (13 NTU). In this study, the infrared spectrum study and analysis has revealed the presence of different functional groups, which are responsible for the coagulation process.
